AES Corp. brings 40 MW energy storage system online

AES Corp. (AES) entered a 40 MW grid-scale energy storage resource into commercial service at Dayton Power and Light’s (DP&L) Tait generating station in Moraine, Ohio.

The project is providing fast-response frequency regulation services to PJM Interconnection to stabilize the grid that serves more than 60 million people.

The facility helps to meet the needs otherwise provided by power generation from inefficient or retiring power plants, reducing overall system emissions and water use while optimizing existing grid resources.

This is AES’ fifth facility to run on its Storage Operating System. This patented operating system, called sOS, is a fast-response control architecture that applies patented performance algorithms to automate the operation of AES-delivered battery-based energy storage arrays, optimizing performance and efficiency for customers, and extending the life of the battery.

The Tait battery array includes more than 800,000 battery cells and connects through DP&L Tait station’s transformers, operated by DP&L and DPL Energy, LLC, through an independent agreement with PJM. The project was deployed from AES’ inventory of battery modules allowing for engineering, construction, and commissioning to occur in less than nine months.
